In June 2013, I sold all of my Nikon gear and bought an OM-D E-M5 and Panasonic 12-35. Last week, while in Mexico, the camera stopped working. One minute it was fine, the next minute it wasn't.

Every time I turn the camera on, it remains powered for 6 - 7 seconds and then shuts down. While it's "on", none of the buttons work. The rear screen shows a live view but none of the usual information is displayed (aperture, ISO, etc). The live-view image also shifts color balance from yellow to natural white, as if it's warming up. I've tried using my spare battery and SD card to see if one of those is at fault but the result is always the same.

I suspect it's a software issue. Anyone else having the same problem??? Any suggestions?

Thanks, Dan
